Copy name from list to another worksheet list

Hi

I need macro which copies row in "Start_list"
from column A to D to another worksheet called "Final_list" to column B:E.
Row to copy is given from cell"K1" and it's start number from column A.
Macro should start with "Add to list" button.
Copied row should be pasted as a next row in "Final_list".
Thanks for any help.

Start_list.xlsm

Great, this is exactly what I wanted.
I wrote some lines to comunicate with users.
1. when the number don't exist on the list - msg.
2. when the number exist on the final list - msg, and here
I found that it paste the same number on the final list.

How to avoid it?
